Abstract

A modular fuel cell system includes a metal base, a plurality of power modules arranged in a row on the base, a fuel processing module and a power conditioning module arranged on at least one end of the row on the base. Each of the plurality of power modules includes a separate cabinet comprising at least one fuel cell stack located in a hot box. The power modules are electrically and fluidly connected to the fuel processing and the power conditioning modules through the base.

Claims

1. A modular fuel cell system, comprising:

a metal base comprising;

a peripheral metal frame; and

metal cross members disposed within the frame and connecting opposing long sides of the frame, such that a hollow space is formed between each pair of cross members;

a plurality of power modules arranged in a row on the base, such that bottoms of the power modules are exposed through the base by the hollow spaces;

a fuel processing module and a power conditioning module arranged on at least one end of the row on the base;

electrical connectors disposed within the frame and electrically connecting the power modules to the power conditioning module;

pipes disposed within the frame and fluidly connecting the power modules to the fuel processing module;

at least one ancillary module located on the base, wherein at least one of the fuel processing, power and the power conditioning modules is at least one of electrically and fluidly connected to the at least one ancillary module through the base; and

a concrete pier or curb located under the base and configured such that the power modules are accessible from below through the base,

wherein;

the cross members are configured such that a top surface of each cross member supports edges of at least two adjacent power modules; and

each of the power modules comprises a separate cabinet comprising at least one fuel cell stack located in a hot box.

2. The system of claim 1, wherein the at least one ancillary module is located adjacent at least one of the fuel processing module and the power conditioning module.

3. The system of claim 2, wherein the at least one ancillary module comprises at least one of a water conditioning module, a power distribution system module or a telemetry module.

4. The system of claim 3, wherein,

the at least one ancillary module comprises the water conditioning module, the power distribution system module and the telemetry module,

the telemetry module is configured to provide system process information to a location remote from the system and to allow remote control of the system, and

the system process information comprises one or more of electricity production, electricity consumption, fuel consumption, water consumption and fuel cell stack temperature.

5. The system of claim 1, wherein the pipes and electrical connectors extend below the cross members, respectively towards the fuel processing module and a power conditioning module.

6. The system of claim 1, wherein the base comprises a plurality of individual sections assembled together to form a unitary base.

7. The system of claim 1, wherein the cross members are configured such that the top surface of each cross member supports edges of at least four adjacent power modules.

8. The system of claim 1, wherein two or more of the fuel processing, power and the power conditioning modules are at least one of electrically and fluidly connected to the at least one ancillary module through the base.

9. The system of claim 1, wherein the fuel processing module comprises a fuel processing module cabinet containing desulfurizer adsorption beds.
